The Marlins are selecting right-hander Bryan Mitchell to the big league roster, relays Jordan McPherson of the Miami Herald (Twitter link). Fellow righty Luis Madero, whose contract had just been selected on Tuesday, has been designated for assignment in a corresponding move. Additionally, infielder Deven Marrero has cleared outright waivers and been assigned to Triple-A Jacksonville, per the MLB.com transactions tracker. Marrero has the right to elect free agency, but he’s previously accepted multiple outright assignments this season, so it seems likely he’ll again report to the Jumbo Shrimp.
Miami signed Mitchell to a minor league contract a few weeks ago, shortly after he was granted his release from a minors deal with the Phillies. Mitchell struggled to a 6.04 ERA with the Phils’ top affiliate in Lehigh Valley, but he’s been far better in brief action in the Miami system. Since being assigned to Jacksonville, Mitchell has tossed twelve innings across five appearances, allowing four runs on ten hits with fourteen strikeouts and six walks.
That decent showing earns Mitchell his first major league call in three years. He began his career as a swing option with the Yankees, pitching with New York from 2014-17. He didn’t find a ton of bottom line success, but Mitchell posted gaudy groundball numbers and showcased plus spin rates on his curveball. That earned him a look in the Padres’ rotation to open the 2018 campaign, but he only managed a 5.42 ERA with a higher walk rate (12.8%) than strikeout rate (11.3%) over 73 innings that year. Mitchell was designated for assignment before the start of the 2019 season. He’s bounced around on a few minor league deals in the years since but hadn’t gotten back to the highest level before today.
Like Marrero, Madero has now been selected to the roster and designated for assignment four times apiece this year. He’s allowed seven runs over six innings between those big league stints. Madero has spent the bulk of the year in Jacksonville, working to a 3.07 ERA across 41 innings at the minors’ top level.
